On Land, Underground and at Sea: The Many Types of

There are several different types of underground mining but the most common variant is called block caving. This type of mining for diamonds was first introduced at the Kimberley mine in 1951. It relies on the kimberlite rock being weaker than the surrounding host rock material. A large tunnel is dug at a shallow angle until the tunnel reaches the ore body. A large chasm or void is extracted

Tailingsfo Backfill of Tailings to Underground Workings

Tailings can be stored below ground in previous worked out voids. The tailings are generally mixed with a binder, usually cement, and then pumped underground to fill voids and help support an underground mine. For example a 'room and pillar' mining operation that uses backfill will be able to extract the insitu pillars containing ore.

What Is Underground Mining?

Jun 26, 2018There are many different underground mining methods that can be implemented, depending on the mineral being mined and the nature of the deposit. No two underground mines are alike. Technology applications and decisions about mining method must consider the type of ore being mined, composition of surrounding rock, shape and orientation of the ore body, geologic features, and

Rocks usually consist of one or more minerals, ranging from single chemical elements to complex com- pounds.

Mining Techniques

Introduction to Mining. Mining literally means extraction.Our Mother Earth has lots of resources deep within her and mining is the method of extracting all these valuable resources from the earth through different means.There are different methods to extract these resources which are found in different forms beneath the earth's surface.It goes without saying that it is the most important

Mining Management Hierarchy

Mining refers to the act of extracting valuable minerals and/ or other materials from the depth of the earth. Naturally these minerals/ materials have a lot of value, and the most common materials mined across the globe include- coal, metals like gold etc., oil, limestone, gemstones, clay etc.

Pros and Cons of Strip Mining

Feb 25, 2015Other forms of mining do not guarantee the same rate of return as strip mining does. Materials are recovered at a rate of up to 90 percent during strip mining, which is a much higher recovery rate than most forms of mining can promise. Tunnel mining, for instance, only offers users a potential recovery rate of 50 percent. 2. Strip Mining Is Faster

Uranium mining

Underground uranium mining is in principle no different from any other hard rock mining and other ores are often mined in association (e.g., copper, gold, silver). Once the ore body has been identified a shaft is sunk in the vicinity of the ore veins, and crosscuts are driven horizontally to the veins at various levels, usually every 100 to 150

3 Methods of Coal Mining

If the coal seams are too deep underground, then deep underground mining is necessary. Deep underground mining methods include Continuous, Longwall, Blast, Retreat Mining and Shortwall Mining. o Continuous Mining: A machine that has a large rotating steel drum with tungsten carbide teeth scrapes coal from the seam.

Methods of Gold Mining

Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers.

Environmental Risks of Mining

Underground Mining. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.

Analysis of world coal production indicates that contributions from surface and underground production are approximately equal. Anthracite seams (less than 10 percent of world coal production) are generally mined by underground methods, whereas lignite seams (25 percent) are most often surface-mined.

THE DIFFERENT TYPES OF UNDERGROUND MINING

THE DIFFERENT TYPES OF UNDERGROUND MINING. Access to coal deposits for underground mines is provided by drift mining. Drift mining cuts horizontally into a hill. Slope mining is cut at an angle from the valley bottom into the hill where the coal is located. Shaft mining is cut straight down deep into the surface by way of a vertical shaft with an elevator to reach the coal seam.

Types of Mine Waste and Disposal Methods

For example, gangue and tailings from mining heavy metals could have a high concentration of sulfides which could cause acid rock drainage to occur. Due to the many variables, mining operations will need to develop their own methods of waste disposal in accordance with regulations pertaining to different types of waste they produce.
